Long term, this testing helped us identify some other areas of the factory ECU where we should focus our future reverse engineering (table/logic discovery) in order to provide the precise control and ease of tunability that the COBB Protuner network demands, even as the power numbers get crazier and crazier as new mods become available over time. We are slowly beginning to really like these cars now as the uncorking process continues. Results vs stock vehicle: +77 wtq (28.8%), +62 whp (24.6%)Īt this point this car is now making a tad more torque and horsepower than a Stage2+Intake 2015 STI on the very same dyno - very impressive for a 2.0L with the diminutive factory turbo. It is likely that the connecting rods will prove to be the long-term weak spot for modified FA20DIT cars, so we decided to call it an afternoon with our engine still intact for now.Įngine/Power Modifications on our 2015 WRX consist of the following: COBB Tuning Accessport V3, COBB Tuning Turboback Exhaust, COBB Tuning SF Intake/Airbox, and a COBB Tuning Front Mount Intercooler Kit, and a COBB Tuning 3-Port EBCS. A bit more time to continue refining the tune would have likely yielded even larger results, but I quickly “chickened out” after realizing how close we were to 350 wtq. We bolted up all of the airflow mods we have on-hand for the car and decided to see what she could do. No records or anything crazy but this thing is definitely one quick WRX now! Like mentioned, e-tuning can take multiple times to get right and also requires some computer skills unless thing can get frustrating.
It’s important for us to have knowledge over how the car will react to common aftermarket upgrades.
While this combo of parts isn’t likely to be an pre-configured OTS “StageX” package that is available from us, we try to do as much hard parts testing as we can to make sure we have a good understanding of the cars. Custom E tuning is also available for the 2002-2007 WRX,2004+Forester XT. We have enjoyed seeing all of the 2015 WRX custom tune results being posted around the ‘net and decided to jump in with our own after a bit of playing around with our car on the Austin R&D dyno today. Custom E-tuning is available Via Accessport For the 2015+WRX, Prices start at 250. Please email us at for details or to see if we can help with your particular model but prices vary from other models.By Marshall on 2015 WRX Tuning Results : 344 WTQ / 313 WHP Please fill out the E-tune form (below) after purchase.

Please read the Technical Support FAQ page for in-depth questions previous customers have had. Our trained and knowledgeable techs can help E-Tune Subaru STi, WRX. We are closed Saturday and Sunday and no emails, revisions or base maps will be answered during this time. We advertise an instructional email within 24 hours and a Base map within 72 hours after purchase Monday through Friday but things can come up to delay that process. This should be done in advance of installing the parts if possible so they can have a base map sitting in the inbox ready. We suggest planning your tune ahead of time to avoid issues and a week prior to the tune to make contact. Includes up to 10 revisions within 30 days as long as the mechanical modifications stay the same during the tuning process. Obviously, situations may come up that exceed the 30-day limit but it will be asked and somewhat expected for a timely response on both our end and the customers to stay on track
